Slag that is produced from induction furnaces that use the Merrill–Crowe process still contains precious metals. In this study, a pyrometallurgical treatment was performed for their recovery in order to realise economic savings and reduce environmental concerns. An analysis was performed to determine the effect of two fluxes (sodium carbonate and anhydrous borax) on the recovery of silver at different temperatures (1373, 1423 and 1473 K). Experiments that used 20% by weight of anhydrous borax at 1473 K showed recoveries up to 99.68% of silver in the metal phase. However, it also showed an increment of impurities in the dore. On the other hand, the silver recovery was 97.2% when 20% of sodium carbonate was used at the same temperature. Additionally, the sodium carbonate flux produced a better quality dore.
